Syntax

[SerializableAttribute]
public class CauchitLinkFunction : ILinkFunction, 
	ICloneable

<SerializableAttribute>
Public Class CauchitLinkFunction
	Implements ILinkFunction, ICloneable

The CauchitLinkFunction type exposes the following members.

Constructors

	Name	Description
	CauchitLinkFunction	Creates a new Cauchit link function.
	CauchitLinkFunction(Double, Double)	Creates a new Cauchit link function.

Properties

	Name	Description
	A	Linear scaling coefficient a (intercept).
	B	Linear scaling coefficient b (slope).

Methods

	Name	Description
	Clone	Creates a new object that is a copy of the current instance.
	Derivative	First derivative of the Inverse(Double) function.
	Derivative2	First derivative of the mean function expressed in terms of it's output.
	Equals	Determines whether the specified object is equal to the current object. (Inherited from Object.)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
	Function	The Cauchit link function.
	GetHashCode	Serves as the default hash function. (Inherited from Object.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	Inverse	The Cauchit mean (activation) function.
	Log	The logarithm of the inverse of the link function.
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	ToString	Returns a string that represents the current object. (Inherited from Object.)

Extension Methods

	Name	Description
	HasMethod	Checks whether an object implements a method with the given name. (Defined by ExtensionMethods.)
	IsEqual	Compares two objects for equality, performing an elementwise comparison if the elements are vectors or matrices. (Defined by Matrix.)
	To(Type)	Overloaded. Converts an object into another type, irrespective of whether the conversion can be done at compile time or not. This can be used to convert generic types to numeric types during runtime. (Defined by ExtensionMethods.)
	ToT	Overloaded. Converts an object into another type, irrespective of whether the conversion can be done at compile time or not. This can be used to convert generic types to numeric types during runtime. (Defined by ExtensionMethods.)

Remarks

The Cauchy link function is associated with the Cauchy distribution.

Link functions can be used in many models, such as in GeneralizedLinearRegression and Support Vector Machines.
